DAYS 1-5 (JUNE 20-24)

Summer begins today at 5:43PM when the solstice occurs. Our weather pattern will support the season as it begins, with today being a very warm to hot and rather humid day. As a safe adjustment I need to add the slight risk of a shower or t-storm to southeastern NH this morning as a boundary sits in the region and has already fired off a downpour north of Concord NH, so if you’re heading into that area or live in southeastern NH, you’ll see some cloudiness and perhaps some brief wet weather before noon today. For the region overall, expect more cloudiness Sunday, but again most shower activity will occur outside the WHW forecast area, with just a stray shower near the South Coast / Cape Cod. Monday through Wednesday will continue the humid theme, with isolated to scattered afternoon showers / t-storms possible both Monday and Tuesday as a cold front slowly approaches from the west. This front will be in the vicinity and an additional disturbance coming along may enhance shower activity in the region by Wednesday. Any rainfall is needed as we continue to run a long term deficit.

TODAY: A brief shower or thunderstorm possible this morning southeastern NH otherwise sunny to partly cloudy. Highs 78-85 South Coast, 86-93 elsewhere. Wind SW 5-15 MPH.

TONIGHT: Partly cloudy except becoming mostly cloudy South Coast. Patchy fog. Humid. Lows 63-70. Wind S under 10 MPH.

DAYS 1-5 (JUNE 19-23)

The day-by-day warm-up continues and today and tomorrow will be the hottest of this week, along with higher humidity. The humidity will remain elevated though the temperature will come down a few notches on Sunday with a little more of a southerly to even southeasterly wind as low pressure passing southeast of the region tweaks the air flow. By Monday, we’re back to a summery southwesterly wind flow, high humidity, and a risk of a shower or storm for all locations as a weak cold front starts to approach the region from the west. That front will be moving very slowly so Tuesday’s weather will be similar, very warm, humid, shower / t-storm risk.

TODAY: Areas of low clouds and patchy fog burning off to sun and a few clouds. Humid. Highs 78-85 South Coast, 86-93 elsewhere. Wind SW 5-15 MPH.

TONIGHT: Areas of low clouds and patchy fog. Humid. Lows 62-69. Wind SW up to 10 MPH.

SATURDAY: Areas of low clouds and patchy fog burning off to sun and a few clouds. Humid. Highs 78-85 South Coast, 86-93 elsewhere. Wind SW 5-15 MPH.

SATURDAY NIGHT: Partly cloudy except becoming mostly cloudy South Coast. Patchy fog. Humid. Lows 63-70. Wind S under 10 MPH.

SUNDAY: Mostly cloudy South Coast. Partly sunny elsewhere. Humid. Highs 73-80 coast, 80-87 inland. Wind S-SE 5-15 MPH.

SUNDAY NIGHT: Partly to mostly cloudy. Patchy fog. Humid. Lows 65-72. Wind S up to 10 MPH.

MONDAY: Partly sunny. Isolated showers and thunderstorms mainly late in the day. Humid. Highs 75-82 South Coast, 83-90 elsewhere. Wind SW 5-15 MPH.

MONDAY NIGHT: Partly cloudy. Patchy fog. Humid. Lows 65-72. Wind SW up to 10 MPH.

TUESDAY: Partly sunny. Isolated showers and thunderstorms in the afternoon. Humid. Highs 75-82 South Coast, 83-90 elsewhere. Wind SW 5-15 MPH.

DAYS 6-10 (JUNE 24-28)

A second front enters the region June 24 and may increase the risk of shower activity that day. The next disturbance may do the same June 26 followed by another at the end of the period. This pattern may seem active but still is not likely to produce all that much rainfall, which is needed. Temperatures variable, mostly near normal overall.

DAYS 11-15 (JUNE 29 – JULY 3)

A zonal (west to east) flow is expected with variable but overall seasonably warm weather but limit opportunities for any shower activity as the overall pattern continues dry.

DAYS 1-5 (JUNE 18-22)

No big changes & one minor adjustment to today’s update. Continuing to see the break-down of what was a blocking pattern, and this process will continue to influence the sensible weather here where we all live, first in the form of a continued warm up and gradual increase in humidity the next three days. We’ll reach “peak” temperature both Friday & Saturday, when some areas will reach or exceed 90. This is not going to be an intense spell of heat with oppressive humidity, but hot and humid enough to be quite noticed, especially since our overall pattern has been on the cooler side. The minor adjustment made involves Sunday’s forecast, which I already had cooler due to a general shift in wind direction as low pressure passes southeast of the region, and that remains today, but I am going to add the risk of a pop up shower favoring southern areas as I think there could be just enough moisture around for that. By Monday, we’re back to a summery southwesterly wind flow, high humidity, and a risk of a shower or storm for all locations as a weak cold front starts to approach the region from the west.

TODAY: Mostly sunny. More humid. Highs 75-82 coast, 83-90 inland. Wind S 5-15 MPH.

TONIGHT: Mostly clear evening. Low clouds forming in some areas overnight. Humid. Lows 60-67. Wind S up to 10 MPH.

FRIDAY: Low clouds favoring the South Coast but areas further north also early in the day, then mostly sunny. Humid. Highs 78-85 coast, 85-92 inland. Wind SW 5-15 MPH.

FRIDAY NIGHT: Areas of low clouds and patchy fog. Humid. Lows 62-69. Wind SW up to 10 MPH.

SATURDAY: Partly cloudy. Humid. Highs 78-85 coast, 85-92 inland. Wind SW 5-15 MPH.

SATURDAY NIGHT: Partly cloudy. Patchy fog. Humid. Lows 63-70. Wind S under 10 MPH.

SUNDAY: Mostly cloudy South Coast with a risk of rain showers. Partly sunny elsewhere. Humid. Highs 72-79 coast, 79-84 inland. Wind SE 5-15 MPH.

SUNDAY NIGHT: Partly to mostly cloudy. Patchy fog. Humid. Lows 65-72. Wind S up to 10 MPH.

MONDAY: Partly sunny. Isolated showers and thunderstorms mainly late in the day. Humid. Highs 77-82 South Coast, 83-88 elsewhere. Wind SW 5-15 MPH.

DAYS 6-10 (JUNE 23-27)

A front from the west slogs its way across the region then sits in the vicinity June 23-26. Expect isolated to scattered showers and thunderstorms June 23 & 25 while impulses of low pressure may bring more general shower activity June 24 & 26, based on current expecting timing. A push of drier air may arrive at the end of the period courtesy high pressure from Canada.

DAYS 11-15 (JUNE 28 – JULY 2)

A zonal (west to east) flow is expected with variable but overall seasonably warm weather but limit opportunities for any shower activity as the overall pattern continues dry.

DAYS 1-5 (JUNE 17-21)

A block in the atmosphere (high pressure to the north, low pressure to the south) is in the process of breaking down but will take about 5 days to do so. For southeastern New England, the result is continued dry weather through Friday with a day-by-day warming trend and a tiny uptick in humidity, starting to be noticeable on Thursday and evening more so on Friday. It will It will become much more noticeable over the weekend as low pressure to the south, while falling apart, sends some of its moisture in this direction. However, that low will maintain enough integrity to help turn our wind from southerly to a little more southeasterly by Sunday, which will put a damper on the summertime temperatures at least for coastal areas. Earlier I had been thinking a front may sneak down from the north, but this no longer looks to the the case. Also, since I think any isolated showers and thunderstorms will be confined to the mountains of western and northern New England this coming weekend, I am keeping them out of the forecast for the WHW forecast area.

TODAY: Mostly sunny. Highs 70-77 coast, 77-84 inland. Wind SE up to 10 MPH.

TONIGHT: Mostly clear. Lows 55-62. Wind SE-S under 10 MPH.

THURSDAY: Mostly sunny. More humid. Highs 75-82 coast, 83-90 inland. Wind S 5-15 MPH.

THURSDAY NIGHT: Mostly clear. Humid. Lows 60-67. Wind S up to 10 MPH.

FRIDAY: Mostly sunny. Humid. Highs 78-85 coast, 85-92 inland. Wind SW 5-15 MPH.

FRIDAY NIGHT: Mostly clear. Humid. Lows 62-69. Wind SW up to 10 MPH.

SATURDAY: Partly cloudy. Humid. Highs 78-85 coast, 85-92 inland. Wind SW 5-15 MPH.

SATURDAY NIGHT: Partly cloudy. Patchy fog. Humid. Lows 63-70. Wind S under 10 MPH.

SUNDAY: Partly sunny. Humid. Highs 72-79 coast, 79-84 inland. Wind SE 5-15 MPH.

DAYS 6-10 (JUNE 22-26)

As a front front the west takes its time moving across the region, we should be back in a south to southwest air flow with higher humidity and a risk of showers and thunderstorms June 22-23. An additional wave of low pressure may bring some wet weather June 24 before drier weather arrives later in the period.

DAYS 11-15 (JUNE 27 – JULY 1)

A zonal (west to east) flow is expected with variable but overall seasonably warm weather but limit opportunities for any shower activity as the overall pattern continues dry.

DAYS 1-5 (JUNE 16-20)

As we count down the final days of spring and arrive at summer on the final day of this 5-day forecast block, we’ll continue to undergo a transition from pleasantly cool weather to warmer and more humid conditions. Still looking at a dry pattern in terms of rainfall, however, with the only risk being an isolated shower or thunderstorm that may pop up in the heat and humidity on Saturday.

TODAY: Mostly sunny. Highs 68-75, coolest coast. Wind E up to 10 MPH.

TONIGHT: Mostly clear. Lows 50-57. Wind SE under 10 MPH.

WEDNESDAY: Mostly sunny. Highs 70-77 coast, 77-84 inland. Wind SE up to 10 MPH.

WEDNESDAY NIGHT: Mostly clear. Lows 55-62. Wind SE-S under 10 MPH.

THURSDAY: Mostly sunny. More humid. Highs 75-82 coast, 83-90 inland. Wind S 5-15 MPH.

THURSDAY NIGHT: Mostly clear. Humid. Lows 60-67. Wind S up to 10 MPH.

FRIDAY: Mostly sunny. Humid. Highs 78-85 coast, 85-92 inland. Wind SW 5-15 MPH.

FRIDAY NIGHT: Mostly clear. Humid. Lows 62-69. Wind SW up to 10 MPH.

SATURDAY: Partly cloudy. Isolated afternoon showers or thunderstorms possible. Humid. Highs 78-85 coast, 85-92 inland. Wind SW 5-15 MPH.

DAYS 6-10 (JUNE 21-25)

Watching for a potential back-door cold front that could make it considerably cooler and potentially mostly cloudy as well for June 21. If this front does not threaten the region, the weather that day would be similar to the day before it. Warm/humid with a risk of showers / t-storms from approaching front June 22. That front may provide a rare risk for a period of rain from late June 23 into June 24 after which dry weather would be back.

DAYS 11-15 (JUNE 26-30)

A zonal (west to east) flow is expected with variable but overall seasonably warm weather but limit opportunities for any shower activity as the overall pattern continues dry.

7:37AM

DAYS 1-5 (JUNE 15-19)

High pressure will continue to dominate the weather through the next 5 days during which time we will see a transition from cool easterly air flow to warm and more humid southerly air flow. By late week, areas away from the coast will be feeling the heat of summer, while temperature remain more modified along the shoreline.

TODAY: Low clouds in much of the region and patchy fog near the coast into mid morning then becoming sunny. Highs 65-70 coast, 70-75 inland. Wind E 5-10 MPH inland, 10-15 MPH coast.

TONIGHT: Clear except patchy ground fog interior lower elevations. Lows 48-55. Wind E under 10 MPH.

TUESDAY: Mostly sunny. Highs 68-75, coolest coast. Wind E up to 10 MPH.

TUESDAY NIGHT: Mostly clear. Lows 50-57. Wind SE under 10 MPH.

WEDNESDAY: Mostly sunny. Highs 68-75 coast, 75-82 inland. Wind SE up to 10 MPH.

WEDNESDAY NIGHT: Mostly clear. Lows 55-62. Wind SE-S under 10 MPH.

THURSDAY: Mostly sunny. More humid. Highs 75-82 coast, 83-90 inland. Wind S 5-15 MPH.

THURSDAY NIGHT: Mostly clear. Humid. Lows 60-67. Wind S up to 10 MPH.

FRIDAY: Mostly sunny. Highs 78-85 coast, 85-92 inland. Wind SW 5-15 MPH.

DAYS 6-10 (JUNE 20-24)

Higher humidity, southerly air flow, and a risk of isolated showers / t-storms June 20. Watching for a potential back-door cold front that could make it considerably cooler and potentially mostly cloudy as well for June 21. Warming back up with a risk of showers / t-storms from approaching front June 22. That front may provide a rare risk for a period of rain from late June 23 into June 24. Low confidence forecast at this time.

DAYS 11-15 (JUNE 25-29)

A more zonal (west to east) flow is expected with variable but overall seasonably warm weather but limit opportunities for any shower activity as the overall pattern continues dry.

1:18AM

DAYS 1-5 (JUNE 14-18)

High pressure will continue to dominate the weather through the next 5 days. Its center to the north initially will continue to result in a general easterly flow, and there should be enough low level moisture for a deck of stratus clouds to roll in from the ocean tonight into Monday morning, at least over eastern sections, especially coastal areas. Most of this should burn off during Monday, however. That’s really the only interruption on a long stretch of fair weather with low humidity and below average temperatures.

TODAY: Partly sunny. Highs 62-67 coast, 67-72 inland. Wind E up to 10 MPH.

TONIGHT: Mostly cloudy. Lows 49-56. Wind E under 10 MPH.

MONDAY: Mostly cloudy morning. Mostly sunny afternoon. Highs 63-70, coolest coast. Wind E up to 5-15 MPH.

MONDAY NIGHT: Mostly clear. Lows 48-55. Wind E under 10 MPH.

TUESDAY: Mostly sunny. Highs 68-75, coolest coast. Wind E up to 10 MPH.

TUESDAY NIGHT: Mostly clear. Lows 50-57. Wind SE under 10 MPH.

WEDNESDAY: Mostly sunny. Highs 68-73 coast, 73-78 inland. Wind SE up to 10 MPH.

WEDNESDAY NIGHT: Mostly clear. Lows 53-60. Wind SE under 10 MPH.

THURSDAY: Mostly sunny. Highs 70-75 coast, 75-80 inland. Wind SE-S 5-15 MPH.

DAYS 6-10 (JUNE 19-23)

High pressure will have shifted to a position east of New England by late in the coming week with an increase in humidity and warmth June 19-21. Generally dry weather is expected overall, but isolated showers may pop up during the June 20-21 weekend with more significant daytime heating occurring. Look for a better chance of showers/thunderstorms June 22 as a front pushes into the region, then drier air arrives for the end of the period.

DAYS 11-15 (JUNE 24-28)

A transition to a more zonal (west to east) pattern, but may be marked with a rare episode of wet weather around June 24. Drier weather follows with temperatures warming to more seasonable levels, but significant heat probably not occurring as the ridge axis is likely to be too far west for that.
